How to Treat Body Acne on Your Back and Chest
Back and chest acne can be stubborn. Learn what causes body acne, the best body washes and treatments, and simple habits to prevent breakouts on your back and chest.
Acne doesn't only show up on your face. The back, chest, and shoulders have plenty of oil glands, which makes them common spots for breakouts. Body acne can be uncomfortable, hard to reach, and frustrating when it's time for summer clothes.
Here's what causes body acne and how to treat and prevent it.
What Causes Body Acne?
Body acne forms the same way facial acne does: excess oil, clogged pores, bacteria, and inflammation. Several factors can make it worse:
- Sweat: Sweat that sits on your skin, especially under tight clothing, can contribute to clogged pores.
- Friction: Backpacks, sports equipment, tight straps, and synthetic workout clothes rub and trap heat.
- Hormones: Hormonal changes affect oil glands on your body as well as your face.
- Hair and body products: Heavy conditioners and body lotions can clog pores on your back and chest.
- Genetics: Some people are simply more prone to body breakouts.
Is It Really Acne?
Some conditions look like acne but need different treatment:
Fungal Acne (Malassezia Folliculitis)
Small, uniform, itchy bumps on the chest, back, and shoulders may be caused by yeast rather than bacteria. It often worsens in heat and humidity and doesn't respond to typical acne treatments. Antifungal treatments are usually needed.
Folliculitis
Inflamed hair follicles can look like small pimples. It can be caused by bacteria, shaving, or hot tubs.
Pro tip: If your bumps are very itchy, look alike, and don't improve with acne products after several weeks, see a dermatologist. You may have fungal acne, which needs a different approach.
Best Treatments for Body Acne
Benzoyl Peroxide Body Wash
Benzoyl peroxide is one of the most effective over-the-counter options for body acne. Look for a 5% to 10% wash. To get the most benefit:
- Apply the wash to affected areas.
- Leave it on for two to five minutes before rinsing.
- Use white towels, as benzoyl peroxide bleaches fabric.
Salicylic Acid
Salicylic acid washes and sprays help unclog pores. Sprays are especially handy for hard-to-reach areas on the back.
Adapalene Gel
Adapalene, a retinoid available over the counter, can be applied to body acne to prevent clogged pores. It can be drying, so start a few times a week.
Alpha Hydroxy Acid Lotions
Lotions with glycolic or lactic acid gently exfoliate and help fade the dark marks body acne often leaves behind.
| Treatment | Best For | Tip |
|---|---|---|
| Benzoyl peroxide wash | Inflamed pimples | Leave on 2–5 minutes |
| Salicylic acid spray or wash | Clogged pores | Good for hard-to-reach areas |
| Adapalene gel | Prevention | Start every other day |
| AHA body lotion | Dark marks, texture | Wear sunscreen on treated areas |
Daily Habits to Prevent Body Acne
- Shower soon after sweating. Don't sit in sweaty clothes after a workout.
- Wear breathable fabrics. Loose cotton or moisture-wicking workout gear can help.
- Wash workout clothes after every use.
- Rinse conditioner thoroughly, and wash your back after conditioning your hair.
- Choose non-comedogenic body lotions and sunscreens.
- Change your sheets weekly.
- Avoid tight straps and backpacks when possible, or clean the straps regularly.
Don't Scrub Too Hard
It's tempting to attack body acne with rough loofahs or harsh scrubs, but aggressive scrubbing can irritate skin and worsen inflammation. Use your hands or a soft washcloth and let your active ingredients do the work.
Fading Dark Marks on the Back and Chest
Body acne often leaves behind dark spots, especially on medium and deep skin tones. To help them fade:
- Use an AHA body lotion a few times a week.
- Protect exposed areas with sunscreen.
- Avoid picking.
- Be patient; body marks often fade more slowly than facial marks.
When to See a Dermatologist
See a dermatologist if your body acne is:
- Deep, painful, or cystic
- Leaving scars
- Not improving after two to three months of over-the-counter treatment
Prescription options may include topical retinoids, oral antibiotics, hormonal therapies, or isotretinoin for severe cases.
Frequently Asked Questions
Why do I get acne on my back but not my face?
Your back has many oil glands and is exposed to sweat and friction from clothing, which can lead to breakouts even if your face stays clear.
Can my shampoo cause back acne?
Yes. Shampoo and conditioner residue can clog pores on your back and shoulders. Rinse thoroughly and wash your body after your hair.
Does sun exposure help body acne?
Sun may temporarily dry out breakouts, but it can worsen dark marks and damage skin. Sunscreen is still important.
The Bottom Line
Body acne responds well to benzoyl peroxide and salicylic acid washes combined with smart daily habits like showering after workouts and wearing breathable clothing. If your bumps are itchy and uniform, consider fungal acne. For stubborn or scarring breakouts, a dermatologist can help.
